Morgues are inherently creepy places, but throw in a possessed cadaver, and you’ve got one hell of a horror movie. The Possession of Hannah Grace follows the long line of exorcism movies released in the late fall and early winter months, but with a twist. The movie, starring Pretty Little Liars‘ Shay Mitchell asks: what happens after an exorcism goes wrong?

Horror movies are nothing if not effective cautionary tales: never drive behind a truck filled with logs, never go to a secluded cabin trip, never split up. The latest lesson from The Possession of Hannah Grace is never allow yourself to be alone in a morgue with a body that died under mysterious circumstances.

But that’s where Shay Mitchell’s former cop Megan Reed finds herself when the body of a young woman who was undergoing an exorcism is brought in. Fresh out of rehab following some unexplained trauma, Megan asserts to the EMT that she can handle herself — despite his dire warnings about the aftereffects of an exorcism gone wrong. “When you’re dead, you’re dead,” Megan declares, before finding that this isn’t quite the case when Hannah Grace’s body snaps back to life, the demon looking for a new vessel to possess.

Originally titled Cadaver, The Possession of Hannah Grace takes the release date slot of James Gunn’s delayed Sony horror movie, reportedly titled Brightburn. The Possession of Hannah Grace is directed by Diederik Van Rooijen and written by Brian Sieve. The cast is rounded out by Kirby Johnson, Stana Katic, Grey Damon, andNick Thune.

Here is the official synopsis for The Possession of Hannah Grace:
